Poured a gallon of antifreeze in oil input top of the engine after draining the oil. Did not start engine. Left open to dry out. A friend needing money did this, but I put the 50/50 next to a quart of oil, I had left the gallon of oil in the trunk.
I'm being told I was lucky that he caught the mistake. It is supposed to be OK in the morning to put the oil in, but I said wait till 12.
What should I do really?
